Bringing Life to Al-karama Dam, Jordan

Jordan has one of the lowest available water supplies in the world; meanwhile Jordan has seen large increase in population and refugee’s fluxes, leading to an increase in water demand [1]. To address this unprecedented water scarcity, Jordan’s water must be used where its social and economic value is highest. Jordan must treat and reuse virtually every drop of water. It is expected to have more th

Identifying a task-invariant cognitive reserve network using task potency

Cognitive reserve (CR) is thought to protect against the consequence of age- or disease-related structural brain changes across multiple cognitive domains. The neural basis of CR may therefore comprise a functional network that is actively involved in many different cognitive processes. To investigate the existence of such a “task-invariant” CR network, we measured functional connectivity in a cog

Consumption of Fish and Long-chain n-3 Polyunsaturated Fatty Acids Is Associated With Reduced Risk of Colorectal Cancer in a Large European Cohort

Background & Aims: There is an unclear association between intake of fish and long-chain n-3 polyunsaturated fatty acids (n-3 LC-PUFAs) and colorectal cancer (CRC). We examined the association between fish consumption, dietary and circulating levels of n-3 LC-PUFAs, and ratio of n-6:n-3 LC-PUFA with CRC using data from the European Prospective Investigation into Cancer and Nutrition (EPIC) coh

Verification of radome problems - Part II

In this paper we analyse the transmission of the electromagnetic field through a dielectric, spherical shell - a simple radome. The source is located inside the shell and consists of a vertical or horizontal electric dipole or a simple array of electric dipoles. A circular PEC (perfect electric conductor) disk is located at the center of the shell and simulates a ground plane. The effect of the sh

Hormonal regulation of sex pheromone biosynthesis in the turnip moth, Agrotis segetum

Pheromone production in the female turnip moth, Agrotis segetum, is under the control of a brain factor. This factor was demonstrated to be a proteinaceous substance termed pheromone biosynthesis activating neuropeptide‐like substance (PBAN‐like substance). The sex pheromone of Swedish A. segetum includes (Z)‐5‐decenyl acetate, (Z)‐7‐dodecenyl acetate, and (Z)‐9‐tetradecenyl acetate as major compo

Substrate specificity of acetyltransferase and reductase enzyme systems used in pheromone biosynthesis by Asian corn borer, Ostrinia furnacalis

The substrate specificity of the acetyltransferase and the reductase enzyme systems used by Ostrinia furnacalis (Lepidoptera: Pyralidae) in pheromone biosynthesis was studied in vivo by topical application of precursors to pheromone glands. Each of the tetradecenols, varying in double bond position (from 7 to 13) and geometry of the double bond, was converted to the corresponding acetate by the ac

Isolation, identification and synthesis of sex pheromone components of the carob moth, Ectomyelois ceratoniae

The sex pheromone of females of the carob moth, Ectomyelois ceratoniae, was identified to be a mixture of (Z,E)-9,11,13-tetradecatrienal, (Z,E)-9,11-tetradecadienal and (Z)-9-tetradecenal in the ratio of 10:1:1. A synthetic blend proved to be attractive. GC/EAD + GC/MS investigations showed (Z,E)-9,11,13-tetradecatrienal, (Z,E)-9,11-tetradecadienal and (Z)-9-tetradecenal to be the sex pheromone of

Risk of bacteremia in patients presenting with shaking chills and vomiting - A prospective cohort study

Chills and vomiting have traditionally been associated with severe bacterial infections and bacteremia. However, few modern studies have in a prospective way evaluated the association of these signs with bacteremia, which is the aim of this prospective, multicenter study. Patients presenting to the emergency department with at least one affected vital sign (increased respiratory rate, increased he

Sex pheromones of three small ermine moths found on the European spindle tree

The sex pheromones produced by virgin females of three species of small ermine moths occurring sympatrically on the European spindle tree were analysed by gas chromatography and the synthetic compounds tested against male moths in the laboratory and field. Pheromone gland extracts of Yponomeuta cagnagellus were shown to contain tetradecyl acetate, (E)‐11‐ and (Z)‐11‐tetradecenyl acetate, tetradeca

Wafer-scale nanofabrication of sub-100 nm arrays by deep-UV displacement Talbot lithography

In this manuscript, we demonstrate the potential of replacing the standard bottom anti-reflective coating (BARC) with a polymethylglutarimide (PMGI) layer for wafer-scale nanofabrication by means of deep-UV displacement talbot lithography (DTL). PMGI is functioning as a developable non-UV sensitive bottom anti-reflective coating (DBARC). After introducing the fabrication process using a standard B
